We now know (via Box Office Mojo) that Sony has set The Mortal Instruments to hit theaters in the U.S. on August 23rd, 2013. That’s probably a wise move, as Clare’s source material is not the best-selling monstrosity that other young adult series-turned-blockbusters are (see: Twilight, The Hunger Games). Not to mention, neither of the film’s attached stars – Lily Collins (Mirror Mirror) and Jamie Campbell Bower (Camelot) – are big enough names so as to make the film more bankable – and thus able to hold its own against some of the “big guns” that will grace the silver screen during the more competitive portion of next summer.
